Diphyus ormenus
(Cresson, 1864)
Diphyus ormenus is a of ichneumonid described by Cresson in 1864. Like other members of the Diphyus, it is a wasp, though specific associations for this species remain poorly documented. The species has been recorded from both Canada and the United States.

Identification
Members of Diphyus can be distinguished from similar ichneumonid by the combination of a long, slender body, elongated ovipositor, and specific wing venation patterns including a distinct areolet in the forewing. -level identification within Diphyus requires examination of detailed morphological characters such as propodeal and coloration patterns; D. ormenus specifically lacks comprehensive published diagnostic descriptions.
Distribution
Recorded from Alberta, Canada (Edmonton, Red Deer, St. Paul) and Vermont, United States. The limited number of documented records suggests either restricted distribution or undercollection.
Ecological Role
As a member of Ichneumonidae, this functions as a , likely contributing to of lepidopteran or other holometabolous insect . Specific ecological impacts are undocumented.

Taxonomic note
The Diphyus is part of the Ichneumoninae, one of the largest and most taxonomically challenging groups within Ichneumonidae. -level in this group relies heavily on subtle morphological characters and is frequently revised.
Data limitations
This is represented by very few occurrence records in public databases (1 iNaturalist observation, limited GBIF records). Published biological information appears to be minimal or absent in readily accessible literature.
